NZS 3910: Delay, Disruption and Extension of Time on Construction Contracts

When:  Jul 31, 2019 from 9:00 AM to 5:00 PM (NZST)
Associated with  New Zealand

This one-day workshop has been developed from training workshops run by the facilitator for contractors. It summarises more advanced and recent Ideas which are vital knowledge for engineers and contractors running 3910 and similar contracts, and for both preparing and responding to claims for extensions of time. The workshop analyses the various entitlements contractors may have for additional time and/or money, such as delays resulting from design changes, interference with progress by others, adverse weather, the need to cooperate with separate contractors, and various other contractual entitlements to more money or more time.

Contractors need to know how best to present and justify such claims. An Engineer administering such a contract will need to respond with an objective and quantified assessment of what additional time or money entitlements should be certified.

Some myths about such assessments are exposed during the workshop:

  • possible ways to make best use of tools like the contractor’s programmes, to assess entitlements
  • the relevance or otherwise of critical paths
  • who owns the float
  • various techniques for the analysis of concurrent delays

More sophisticated tools that could be used (such as prospective or as-built programme analysis) are explained, along with lessons learned from recent court litigation on the topic.

Following this course, participants will:

  • learning more formal processes for such claims and their responses
  • reviewing lessons learned from recent disputes and litigation
  • hearing how to improve the chance of success for contractors claims
  • how to justify appropriate responses to claims by contract administrators
  • how to use or to abuse tods like Ms-Project, Primavera
  • being aware of some of the advice given in recent industry conferences on this important topic
  • learning about ideas to be found in the recent revision of the Society of Construction Law’s ‘Delay and Disruption Protocol’
  • knowing how this relates to NZS 3910, FIDIC, NEC3 and other standard contracts that find use on New Zealand projects

Workshop Facilitator
Andrew Brickell is a very experienced construction contracts practitioner and presenter, who also covers other topics in IPWEA’s training programme (expanded upon in the course brochure.) Andrew was the IPENZ and ACENZ representative on the Standards NZ 3910 revision committee, so he is well placed to explain the reasons for the important changes introduced by the 2013 revisions.
